Reception
Audrey Im of Anime Trending reviewed the first episode of the series. While praising the anime for its humor, she considered that Iwata's insecurity of her size was emphasized in several scenes, writing "Though Iwata's love for food and insecurity of her size is highlighted in several scenes [...] [I] appreciated how the show doesn't seem to make fun of these qualities. Iwata's fatness and tallness aren't being poked at under the guise of comedic relief; instead, her sensitivity toward these traits is displayed in a fashion that is so emblematic of teenage insecurity."
